Prediction of myofascial pelvic pain syndrome based on random forest model.

Objective: The objective is to construct a random forest model for predicting the occurrence of Myofascial pelvic pain syndrome (MPPS) and compare its performance with a logistic regression model to demonstrate the superiority of the random forest model.

Methods: We retrospectively analyze the clinical data of female patients who underwent pelvic floor screening due to chronic pelvic pain at the Pelvic Floor Rehabilitation Center of the Third Affiliated Hospital of Zhengzhou University from January 2021 to December 2023. A total of 543 female patients meeting the study's inclusion and exclusion criteria are randomly selected from this dataset and allocated to the MPPS group.

Subsequent ovarian yolk sac tumor after operation of ovarian mature teratoma: a case report and review of the literature.

Ovarian mature teratoma represents a benign ovarian tumor, while ovarian yolk sac tumor (YST, endodermal sinus tumor) is a rare malignant tumor predominantly affecting young women, often associated with a grim prognosis post-metastasis. Both ovarian mature teratoma and ovarian YST are germ cell tumors. There are few studies on the correlation between ovarian YST and mature teratoma.

Comparison of efficacy between laparoscopic pectopexy and laparoscopic high uterosacral ligament suspension in the treatment of apical prolapse-short term results.

To compare the clinical efficacy of laparoscopic pectopexy and laparoscopic high uterosacral ligament suspension in women suffering from apical prolapse. The clinical data of 170 patients with apical prolapse (POP-Q score ≥ II) treated in the Third Affiliated Hospital of Zhengzhou University from January 2018 to July 2020 were retrospectively analyzed to assess the clinical efficacy of three surgical methods [laparoscopic pectopexy with uterine preservation, laparoscopic pectopexy with hysterectomy, laparoscopic high uterosacral ligament suspension (LHUSLS) with hysterectomy]. Patients were divided into three groups depending on Surgical methods: laparoscopic uterine pectopexy group (n = 23), laparoscopic pectopexy with hysterectomy group (n = 78) and LHUSLS with hysterectomy group (n = 69).

MicroRNA let‑7d‑5p rescues ovarian cancer cell apoptosis and restores chemosensitivity by regulating the p53 signaling pathway via HMGA1.

Ovarian cancer (OC) is the gynecological malignancy type with the highest mortality rate in females. The regulatory effect of microRNAs (miRs) on their target genes serves a key role in tumor development. Therefore, in the present study, whether miR let‑7d‑5p targeting high mobility group A1 (HMGA1) regulated biological characteristics and chemosensitivity of OC cells by mediating the p53 signaling pathway was investigated.

lncRNA WT1-AS inhibits the aggressiveness of cervical cancer cell via regulating p53 expression via sponging miR-330-5p.

Background: Emerging evidences have demonstrated that lncRNAs play vital roles in various pathological processes, including cancer. The lncRNA WT1 antisense RNA (WT1-AS) serves as a tumor suppressor in various cancers. Nevertheless, the expression and precise function of WT1-AS in cervical carcinoma still remain not yet investigated.

Annexin A2 inhibition suppresses ovarian cancer progression via regulating β-catenin/EMT.

Annexin A2 is a member of the Annexin family that acts as a Ca2+-dependent phospholipid and membrane binding protein, which is associated with the survival and spread of multiple neoplasms. However, the function of Annexin A2 in ovarian cancer progression remains unclear. In this study, we aimed to investigate the role and underlying molecular mechanism of Annexin A2 in cell proliferation and invasion in ovarian cancer.

[Comparison among measures to prevent intrauterine adhesions after artificial abortion].

Objective: To investigate the clinical efficacy of oral medicine and sodium hyaluronate in prevention of intrauterine adhesions after artificial abortion.


Methods: A total of 572 patients with early pregnancy termination through artificial abortion, who experienced two or more times of abortion, were retrospectively analyzed. Patients were randomly and voluntarily divided into 4 groups: an artificial cycle group, a drospirenone and ethinylestradiol tablets group, a sodium hyaluronate group, and a control group.

[The expression of RhoC and Ki67 in cervical intraepithelial neoplasia and squamous carcinoma of cervix].

Objective: To detect the expression of RhoC and Ki67 in squamous carcinoma of cervix and to reveal the correlation of RhoC and Ki67 with clinic pathological parameters of cervix carcinoma.

Methods: The expressions of RhoC and Ki67 were evaluated in 26 cases of cervical intraepithelial neoplasia (CIN) and 57 cases of squamous carcinoma of cervix(SCC) by immunohistochemistry, while 14 cases of normal cervical epithelium(NCE) were taken as control.

Results: Immunohistochemical staining demonstrated RhoC expression in 82.
